I installed the latest kernel version (3.0.0-15) through the Muon package manager of Kubuntu 11.10 but when I reboot the system it doesn't appear on grub list so I can use only the 3.0.0-12 kernel version. Synaptic reports that it's installed the kernel 3.0.0-14 version too but it doesn't appear too. The 3.0.0-14 and 3.0.0-15 versions didn't have the kernel image installed so I tried to install them but they don't appear on grub list in any case. Any idea? Many thanks in advance!

The package manager should do this by default. Looking old logs:
